<h1>Certificate Verification</h1>

 <p class="para">
  When calling a function that will verify a signature/certificate, the
  <em><code class="parameter">cainfo</code></em> parameter is an array containing file and
  directory names that specify the locations of trusted CA files. If a
  directory is specified, then it must be a correctly formed hashed
  directory as the <strong class="command">openssl</strong> command would use.
